Updated ethereal packages are now available that fix multiple security
vulnerabilities which may allow attackers to make Ethereal crash by
injecting an intentionally malformed packet onto the wire or by convincing
someone to read a malformed packet trace file. It is not known if these
issues could allow arbitrary code execution.

Ethereal is a network traffic analyzer for Unix-ish operating systems.

The SMB dissector in Ethereal before 0.10.0 allows remote attackers to
cause a denial of service via a malformed SMB packet that triggers a
segmentation fault during processing of Selected packets. The Common
Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name
CAN-2003-1012 to this issue.

The Q.931 dissector in Ethereal before 0.10.0 allows remote attackers to
cause a denial of service (crash) via a malformed Q.931, which triggers a
null dereference. The Common Vulnerabilities and Exposures project
(cve.mitre.org) has assigned the name CAN-2003-1013 to this issue.
Users of tcpdump should update to these update packages, which contain a
backported security patch that corrects this issue.

Fedora Legacy would like to thank Christian Pearce for providing a
backported fix for Red Hat Linux 7.2, 7.3, and 8.0.

4. Solution:

Before applying this update, make sure all previously released errata
relevant to your system have been applied.

To update all RPMs for your particular architecture, run:

rpm -Fvh [filenames]

where [filenames] is a list of the RPMs you wish to upgrade. Only those
RPMs which are currently installed will be updated. Those RPMs which are
not installed but included in the list will not be updated. Note that you
can also use wildcards (*.rpm) if your current directory *only* contains
the desired RPMs.

Please note that this update is also available via yum and apt. Many
people find this an easier way to apply updates. To use yum issue:

yum update

or to use apt:

apt-get update; apt-get upgrade

This will start an interactive process that will result in the appropriate
RPMs being upgraded on your system. This assumes that you have yum or
apt-get configured for obtaining Fedora Legacy content. Please visit
http://www.fedoralegacy.org/download for directions on how to configure
yum and apt-get.
